在程序開發(fā)時，有時候需要屏幕保持點亮/常亮及解鎖狀態(tài)。比方說，鬧鐘響起時需要點亮和解鎖屏幕或者實現(xiàn)一個一鍵實現(xiàn)屏幕鎖屏（鎖定）效果。具體代碼如下： 1、Android屏幕常亮/點亮 //保持屏幕常亮 PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); mWakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, LOCK_TAG); mWakeLock.acquire(); //釋放屏幕常亮鎖 if(null != mWakeLock) { mWakeLock.release(); } 2、Android屏幕解鎖和鎖定 //屏幕解鎖 KeyguardManager keyguardManager = (KeyguardManager)getSystemService(KEYGUARD_SERVICE); KeyguardLock keyguardLock = keyguardManager.newKeyguardLock(LOCK_TAG); keyguardLock.disableKeyguard(); //屏幕鎖定 keyguardLock.reenableKeyguard(); 3、相關(guān)權(quán)限 <uses-permission android:name="android.permission.DISABLE_KEYGUARD" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> |
